Neighbor location discovery with directional antennas in a mesh network

摘要: Disclosed is a Neighbor Location Discovery Protocol (NLDP) that determines the relative locations of nodes in mesh network. In one embodiment, NLDP can be implemented for an ad-hoc wireless network where are equipped with directional antennas and not able to use GPS. While relies on having at least two RF transceivers, it offers significant advantages over previously proposed protocols employ only transceiver. antenna hardware simple, easy implement, readily available. Further, exploits host node's ability operate simultaneously non-overlapping channels quickly converge neighbor's location. limited by range control channel, which operates omni-directional fashion. However, choosing low frequency band, high power, data rate, channel increased match channel.
